Description

本発明は、パンタグラフ構造に関し、特にキーボードのキー用パンタグラフ構造に関する。   The present invention relates to a pantograph structure, and more particularly to a pantograph structure for a keyboard key.

従来のキーボードのキー構造の伝達機構は、パンタグラフ伝達機構が用いられ、内枠と外枠とを含む。内枠には、対称的な側の延伸方向に沿って、接続軸が設けられている。一方、外枠には、接続軸に対応する位置に、軸穴が設けられている。これにより、内枠と外枠とは、軸穴を介して連結されている。このような構成を有する伝達機構は、製造コストが高く、品質を確保しにくく、組み立て作業が困難で、大量の人員が必要で、製造効率が悪く、軸穴の連結箇所のギャップにより伝達が緩慢になりやすい。   A conventional keyboard key structure transmission mechanism uses a pantograph transmission mechanism and includes an inner frame and an outer frame. The inner frame is provided with a connecting shaft along the extending direction on the symmetrical side. On the other hand, the outer frame is provided with a shaft hole at a position corresponding to the connecting shaft. Thereby, the inner frame and the outer frame are connected via the shaft hole. The transmission mechanism having such a configuration is high in manufacturing cost, difficult to ensure quality, difficult to assemble, requires a large amount of personnel, has low manufacturing efficiency, and transmission is slow due to a gap in the connecting part of the shaft hole. It is easy to become.

本発明の目的は、コストが高く、品質を確保しにくく、組み立て作業が困難で、構造的に緩みやすいという従来のパンタグラフ構造の問題を解決する、キーボードのキー用のパンタグラフ構造を提供することである。   An object of the present invention is to provide a pantograph structure for a keyboard key that solves the problems of the conventional pantograph structure that is expensive, difficult to ensure quality, difficult to assemble, and structurally loose. is there.

本発明のキーボードのキー用のパンタグラフ構造は、弾性を有する接続柱で固定的に接続される内枠と外枠を含み、キーが押圧されると、内枠と外枠とが下方に押圧され、接続柱が弾性変形し、キーがリリースされると、接続柱の弾性回復力で内枠と外枠とが初期状態に戻り、キーの伝達を実現する。   The pantograph structure for keys of the keyboard of the present invention includes an inner frame and an outer frame fixedly connected by a connecting pillar having elasticity, and when the key is pressed, the inner frame and the outer frame are pressed downward. When the connecting column is elastically deformed and the key is released, the inner frame and the outer frame are returned to the initial state by the elastic recovery force of the connecting column, thereby realizing the key transmission.

当該外枠及び内枠は、矩形の枠体であり、内枠は、外枠の枠体の中に位置し、内枠は、一対の内枠底部壁と一対の内枠側方壁を含み、外枠は、一対の外枠底部壁と一対の外枠側方壁とを含み、接続柱で隣接する内枠側方壁と外枠側方壁とが固定的に接続される。隣接する内枠側方壁と外枠側方壁とは、接続柱の軸方向の両端にそれぞれ固定的に接続されることが更に好ましい。   The outer frame and the inner frame are rectangular frames, the inner frame is located in the outer frame, and the inner frame includes a pair of inner frame bottom walls and a pair of inner frame side walls. The outer frame includes a pair of outer frame bottom walls and a pair of outer frame side walls, and the inner frame side wall and the outer frame side wall which are adjacent to each other by a connection column are fixedly connected. More preferably, the adjacent inner frame side wall and outer frame side wall are fixedly connected to both ends of the connecting column in the axial direction.

内枠、外枠、及び接続柱は、一体的に成形される。この場合、パンタグラフ機構は、二個取り成形工程で成形されてもよい。   The inner frame, the outer frame, and the connection pillar are integrally formed. In this case, the pantograph mechanism may be formed by a two-piece forming process.

接続柱は、弾性材料から形成され、弾性材料は、プラスチック、ゴムなどである。   The connecting column is made of an elastic material, and the elastic material is plastic, rubber, or the like.

従来技術に比較し、本発明の明らかな利点は、以下の通りである。（１）本発明は、キーボードのキーに用いられるパンタグラフ構造であり、内枠と外枠とは、弾性接続柱で固定的に接続され、弾性材料の変形と弾性回復力で内枠と外枠との伝達が実現され、伝達構造が緊密で、キーボードのキーに用いられる場合、キーの品質を著しく向上させる。（２）本発明のパンタグラフ構造は、二個取り成形工程で成形されることが可能で、内枠と外枠とは、同一の材料で射出成形される。内枠と外枠とは、二色射出成形で成形されることも可能で、内枠と外枠とが射出成形されてから、異なる材料で弾性を有する接続柱が射出成形される。これにより、人員にかかるコストを大幅に低下させ、製造効率を向上させ、所定の品質も確保することができる。   Compared to the prior art, the obvious advantages of the present invention are as follows. (1) The present invention is a pantograph structure used for a key of a keyboard, and an inner frame and an outer frame are fixedly connected by an elastic connecting column, and the inner frame and the outer frame are deformed by elastic material and elastic recovery force. When the transmission structure is tight and the transmission structure is used for a keyboard key, the quality of the key is remarkably improved. (2) The pantograph structure of the present invention can be molded in a two-piece molding process, and the inner frame and the outer frame are injection-molded with the same material. The inner frame and the outer frame can be formed by two-color injection molding. After the inner frame and the outer frame are injection-molded, a connecting column having elasticity with different materials is injection-molded. Thereby, the cost concerning personnel can be significantly reduced, the production efficiency can be improved, and the predetermined quality can be ensured.

以下、図面を参照しながら、本発明の技術手段を更に説明する。   The technical means of the present invention will be further described below with reference to the drawings.

図１に示すように、本発明のキーボードのキー用パンタグラフ構造は、外枠２と内枠１を含み、さらに、外枠２と内枠１との間に、外枠２と内枠１とを固定的に連結する連結柱３を含む。連結柱３は、弾性を有する弾性材料からなり、たとえば、弾性材料としてプラスチック、ゴムが挙げられる。   As shown in FIG. 1, the key pantograph structure of the keyboard of the present invention includes an outer frame 2 and an inner frame 1, and further, between the outer frame 2 and the inner frame 1, The connection pillar 3 which connects together is included. The connecting column 3 is made of an elastic material having elasticity, and examples of the elastic material include plastic and rubber.

外枠２、内枠１は、矩形の枠体であり、内枠１は、外枠２の枠体の中に位置する。   The outer frame 2 and the inner frame 1 are rectangular frames, and the inner frame 1 is located in the frame of the outer frame 2.

図２と図３に示すように、内枠１は、一対の内枠底部壁１１と一対の内枠側方壁１２とを含む。外枠２は、一対の外枠底部壁２１と一対の外枠側方壁２２とを含む。接続柱３は、隣接する内枠側方壁１２と外枠側方壁２２との間に位置し、内枠側方壁１２と外枠側方壁２２とを固定的に連結する。接続柱３の軸方向の両端は、隣接する内枠側方壁１２と外枠側方壁２２とに固定的に連結してもよい。   As shown in FIGS. 2 and 3, the inner frame 1 includes a pair of inner frame bottom walls 11 and a pair of inner frame side walls 12. The outer frame 2 includes a pair of outer frame bottom walls 21 and a pair of outer frame side walls 22. The connecting column 3 is located between the adjacent inner frame side wall 12 and the outer frame side wall 22 and fixedly connects the inner frame side wall 12 and the outer frame side wall 22. Both ends of the connecting column 3 in the axial direction may be fixedly connected to the adjacent inner frame side wall 12 and outer frame side wall 22.

本発明のパンタグラフ構造は、キーボードのキーに用いられる。初期状態において、内枠１と外枠２とは、一定の角度で交差し、接続柱３は、押圧力を受けていない状態にある。キーが押圧されると、内枠１と外枠２とは下方に押圧される。この、押圧力により、内枠１と外枠２とは回転し、内枠１と外枠２との交差角度が徐々に小さくなる。これにより、接続柱３は、内枠１と外枠２とに引っ張られて、弾性変形する。キーがリリースされると、押圧力が作用しなくなり、接続柱３は弾性回復力で初期形状に復帰するとともに、内枠と外枠とを初期状態に戻す。このようにして、キーに作用する押圧力がキーに伝達する。   The pantograph structure of the present invention is used for keys on a keyboard. In the initial state, the inner frame 1 and the outer frame 2 intersect at a certain angle, and the connecting column 3 is in a state where it does not receive a pressing force. When the key is pressed, the inner frame 1 and the outer frame 2 are pressed downward. Due to this pressing force, the inner frame 1 and the outer frame 2 rotate, and the intersection angle between the inner frame 1 and the outer frame 2 gradually decreases. As a result, the connecting column 3 is pulled by the inner frame 1 and the outer frame 2 and elastically deforms. When the key is released, the pressing force does not act, and the connecting column 3 returns to the initial shape by the elastic recovery force, and returns the inner frame and the outer frame to the initial state. In this way, the pressing force acting on the key is transmitted to the key.

従来の軸穴を介して連結されたパンタグラフ構造に比べて、本発明のパンタグラフ構造は、軸穴を有しておらず、接続柱３の弾性変形と弾性回復力で伝達が実現され、伝達工程が緊密である。キーボードのキーに用いられる場合、キーの伝達品質を著しく向上させる。内枠１と外枠２との間には、弾性を有する接続柱３のみが設けられているため、組立作業を容易に行える。   Compared to the conventional pantograph structure connected through a shaft hole, the pantograph structure of the present invention does not have a shaft hole, and transmission is realized by elastic deformation and elastic recovery force of the connecting column 3, and a transmission process. Is close. When used for a keyboard key, the transmission quality of the key is remarkably improved. Since only the connecting column 3 having elasticity is provided between the inner frame 1 and the outer frame 2, the assembling work can be easily performed.

内枠１、外枠２、及び接続柱３は、一体的に成形するようにしてもよい。この場合、本発明のパンタグラフ機構は、二個取り成形工程で成形されることが可能で、内枠１と外枠２とは、同一の材料で射出成形され、接続柱３は、異なる材料で射出成形される。パンタグラフ機構は、二色射出成形で成形されることも可能で、内枠１と外枠２とが射出成形されてから、弾性のある接続柱が射出成形される。これにより、従来工程に比べて、製造工程を自動化することができ、組立と製造コストを大幅に抑制することができ、製造効率を向上させ、製品の品質の確保も容易となる。   The inner frame 1, the outer frame 2, and the connection column 3 may be integrally formed. In this case, the pantograph mechanism of the present invention can be molded in a two-piece molding process. The inner frame 1 and the outer frame 2 are injection-molded with the same material, and the connecting column 3 is made of different materials. Injection molded. The pantograph mechanism can also be molded by two-color injection molding. After the inner frame 1 and the outer frame 2 are injection molded, an elastic connecting column is injection molded. Thereby, compared with the conventional process, the manufacturing process can be automated, the assembly and manufacturing costs can be greatly suppressed, the manufacturing efficiency can be improved, and the product quality can be easily ensured.
